A science teacher drove 10 miles to school in 20 minutes He drove the 10 miles home in 30 min His average velocity was ms?
He drove 20 miles in 50 min. so average was 20 x 60/50 = 24 mph
What is the acceleration in science if you know average speed and time?
If you know average speed then you cannot determine the acceleration: the very nature of being a average hides all the increases and decreases in speed which are the accelerations (technically, acceleration is change of speed in a direction). All average speed tells you is the constant speed at which you require to travel to cover the given distance in the given time; as the speed is constant, the acceleration is zero.
Mr Hoffmana science teacher drove 10 miles to school in 20 minutes He drove the 10 miles home in 30 min His average velocity was?
Well, speed is equal to distance over time (s = d/t) However, velocity means speed WITH direction. This means that the teacher's drive to school would be a positive velocity, but the drive back would be a negative one. Now, let's calculate velocities using the s = d/t formula! Distance to school from home: speed = distance/time speed = +10 miles/20 minutes speed = 1/2 miles per minute Distance from school to home: speed = distance/time speed = -10miles/20 minutes speed = -1/3 miles per minute Note: the velocity towards home will be negative since we are travelling in the opposite direction of the distance to school (which is positive) We have our two velocities- let's calculate the average! 1/2 -1/3 = 1/6 1/6 divided by 2 = 1/12 Thus, our average velocity is 1/12 miles per minute! You can convert this into decimal values if required. Hope this helped! (:
What factors are involved in determining stopping distance of a toy car?
arent u a science student? its simple. time,initial velocity,accelaration the formula is; v2=u2+2as here v is final velocity u is innitial velocity a is accelaration s will be3 the stopping distance okkkk!!
What is the unit of measurement of velocity?
The standard unit used in science is meters/second, but kilometers/hour is also quite common. Actually you can divide any unit of length by any unit of time, and get a valid unit for speed or velocity.
Mr Hoffman is a science teacher that drove 10 miles to school in 20 minutes and he drove the 10 miles home in 30 min so his average velocity was ms?

What is the relation of velocity to health and science?
Velocity is related to health in the sense that high velocity collisions are more damaging than low velocity collisions. Velocity is related to science in the sense that Newtonian mechanics deals with velocity.
What is a good question about science?
What is Velocity
Science words that start with a v?
Velocity and volume are science words.
What has the author A Hoffman written?
A. Hoffman has written: 'Thermodynamic Theory of Latent Image Formation (Progress Reports in Imaging Science & Technology)' 'The Golfer's Catalog'
How much minutes in a average persons life?
There are about 52,594,877 minutes in an averages person life. 100 years old will be the average life span of a human being in earth as our health science increases.

What is acceleration in science?
Acceleration is any change in velocity. Velocity is the speed and direction of motion.
